Because a size of the physical display screen 20 is limited, all of the software icons of the virtual display screen 30 cannot be displayed on the physical display screen 20 at one time. In one embodiment, as shown in FIG. 5, the software icons within a virtual display area 32 of the virtual display screen 30 are displayed on the physical display screen 20 of the handheld device 2.
The software interface display system 24 is used to update the software icons (software interface) displayed on the physical display screen 20 according to movements of the handheld device 2. In one embodiment, the software interface display system 24 may include computerized instructions in the form of one or more programs that are executed by the processor 25 and stored in the storage device 23 (or memory). A detailed description of the software interface display system 24 will be given in the following paragraphs.
FIG. 2 is a block diagram of function modules of the software interface display system 24 included in the handheld device 2. In one embodiment, the software interface display system 24 may include one or more modules, for example, an initial state setting module 240, a state detecting module 241, a state analyzing module 242, and a software icon updating module 243. In general, the word “module”, as used herein, refers to logic embodied in hardware or firmware, or to a collection of software instructions, written in a programming language, such as, Java, C, or assembly. One or more software instructions in the modules may be embedded in firmware, such as in an EPROM. The modules described herein may be implemented as either software and/or hardware modules and may be stored in any type of non-transitory computer-readable medium or other storage device. Some non-limiting examples of non-transitory computer-readable medium include CDs, DVDs, BLU-RAY, flash memory, and hard disk drives.
FIG. 3 is a flowchart of one embodiment of a method for displaying a software interface on the physical display screen 20 of the handheld device 2. Depending on the embodiment, additional steps may be added, others removed, and the ordering of the steps may be changed.
In block S10, the initial state setting module 240 sets an initial state of the handheld device 2 and initial software icons corresponding to the initial state, and displays the initial software icons on the physical display screen 20. The initial state setting module 240 stores an initial angle and an initial direction of the handheld device 2 into the storage device 23 or the memory. In one embodiment, the initial state may correspond to the initial angle and the initial direction or other kinds of parameters of the handheld device 2 which are detected by the electronic gyroscope 22. The initial software icons are specified icons within the virtual display area 32 when the virtual display area 32 is located at an initial position (e.g., a center) of the virtual display screen 30, where a virtual size of the virtual display area 32 is equal to an actual size of the physical display screen 20.
For example, as shown in FIG. 5, the virtual size of the virtual display area 32 is determined as 4×4 icon array, and the actual size of the physical display screen 20 is also determined as 4×4 icon array. Then, the initial software icons within the virtual display area 32 are determined to be “A1B6, A1B7, A1B8, A1B9, A2B6, A2B7, A2B8, A2B9, A3B6, A3B7, A3B8, A3B9, A4B6, A4B7, A4B8, A4B9”, where the software icons within the virtual display area 32 are determined to be initial icons need to be displayed on the physical display screen 20. In one embodiment, a position of the virtual display area 32 is moveable when the handheld device 2 is moved so that the software icons displayed on the physical display screen 20 are changed in response to the movements of the handheld device 2.
In block S11, the state detecting module 241 determines a current state of the handheld device 2 detected by the electronic gyroscope 22 at each preset time interval. In one embodiment, the current state of the handheld device 2 may correspond to, a current angle and a current direction of the handheld device 2 which are detected by the electronic gyroscope 22. In other embodiments, the initial state or the current state of the handheld device 2 may be detected by other electronic components, such as an electronic compass.
In block S12, the state analyzing module 242 determines a movement direction and a movement angle of the handheld device 2 between the current state and the initial state of the handheld device 2. For example, the state analyzing module 242 determines the movement direction and the movement angle related with the initial state of the handheld device 2 by comparing the initial angle and the initial direction with the current angle and the current direction of the handheld device 2 correspondingly.
In block S13, the software icon updating module 243 determines current software icons of the physical display screen 20 according to the movement direction and the movement angle of the handheld device 2.
The software icon updating module 243 determines a movement step length of the virtual display area 32 according to the movement angle of the handheld device 2. For example, the virtual display area 32 moves one step length when the movement angle of the handheld device 2 is added six degrees. The virtual display area 32 stops moving when the movement angle of the handheld device 2 reaches a preset maximum angle (e.g., 30 degrees).
The software icon updating module 243 moves the virtual display area 32 from the initial position to a current position on the virtual display screen 30 according to the determined movement step length, and determines the current software icons within the virtual display area 32 at the current position.
In block S14, the software icon updating module 243 displays the current software icons on the physical display screen 20 of the handheld device 2.
For example, as shown in FIG. 6, suppose that the handheld device 2 is rotated left, the virtual display screen 30 includes an array of software icons of 4×14 , the actual size of the physical display screen 20 is an array of software icons of 4×4. The virtual display area 32 reaches a border position (i.e., broken line) of the virtual display screen 30 when the virtual display area 32 moves five step lengths towards left (or right). If the preset maximum angle is 30 degrees, the handheld device 2 needs to rotate six degrees (30/5=6) towards left (or right) to move the virtual display area 32 one step length towards left (or right).
If the movement direction of the handheld 2 is left, represents the movement angle of the handheld device 2.
If −6 degrees<α<0, the software icon updating module 243 determines that the handheld device 2 is not moved (ignores the movement of the handheld device 2), and the virtual display area 32 is still located on the initial position (in the center of the virtual display screen 30).
If −12 degrees<α≦−6 degrees, the software icon updating module 243 moves the virtual display area 32 one step length toward left from the initial position.
If −18 degrees<α≦−12 degrees, the software icon updating module 243 moves the virtual display area 32 two step lengths toward left from the initial position.
If −24 degrees<α≦−18 degrees, the software icon updating module 243 moves the virtual display area 32 three step lengths toward left from the initial position.
If −30 degrees<α≦−24 degrees, the software icon updating module 243 moves the virtual display area 32 four step lengths toward left from the initial position.
If α≦−30 degrees, the software icon updating module 243 moves the virtual display area 32 five step lengths toward left from the initial position.
If the movement direction of the handheld 2 is right, “α” represents the movement angle of the handheld device 2.
If 0<α<6 degrees, the software icon updating module 243 determines that the handheld device 2 is not moved (ignores the movement of the handheld device 2), and the virtual display area 32 is still located on the initial position (in the center of the virtual display screen 30).
If 6 degrees<α<12 degrees, the software icon updating module 243 moves the virtual display area 32 one step length toward right from the initial position.
If 12 degrees<α<18 degrees, the software icon updating module 243 moves the virtual display area 32 two step lengths toward right from the initial position.
If 18 degrees<α<24 degrees, the software icon updating module 243 moves the virtual display area 32 three step lengths toward right from the initial position.
If 24 degrees<α<30 degrees, the software icon updating module 243 moves the virtual display area 32 four step lengths toward right from the initial position.
If 30 degrees<α, the software icon updating module 243 moves the virtual display area 32 five step lengths toward right from the initial position.
FIG. 7 is a schematic diagram of an example of the virtual display screen 30 in a second embodiment. As shown in FIG. 7, the virtual display screen 30 includes an array of software icons of 14×4 (14 rows, 4 ranks). The virtual display area 32 reaches the border position (i.e., broken line) of the virtual display screen 30 when the virtual display area 32 moves five step lengths towards up (or down). If the preset maximum angle is 30 degrees, the handheld device 2 needs to rotate six degrees (30/5=6) towards up (or down) to move the virtual display area 32 one step length towards up (or down).
A movement of the virtual display area 32 in the second embodiment is similar to the first embodiment.
In other embodiments, the virtual display area 32 may move upper left, bottom left, upper right, and bottom right. For example, as shown in FIG. 8, the virtual display screen 30 includes an array of software icons of 8×10 (8 rows, 10 ranks). The virtual display area 32 may be moved toward upper left from the initial position (the center of the virtual display screen 30).
